GAS-HEATER.

Application filed July 11, 1919.

To all whom it may concern: 7

Be it known that I, Gnonen GHEOKLEY, a citizen of Great Britain, residing at Winthrop, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Gas-Heaters, of which the following is a specification.

This invention relates to gas heaters, and the main object thereof is to provide such a heater which will completely consume the gaseous fuel so that noobjeetionable odors or dangerous gases are emitted from the heater,

Another object is to provide a heater of this character, which while producing a maximum amount of heat consumes a minimum quantity of gas. I

Another object is toso construct such a heater that it will'be compact and simple and may be readily transported from place to place.

\Vith the foregoing and other objects in view, which will, appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing is 1llustrated a central vertical sectional perspective view of a heater constructed in accordance with this'invention.

In the embodiment illustrated, a sheet metal casing 1 is shown, which is preferably cylindrical in form, although not necessarily of this configuration. This casing has a closed bottom 2 and a fiat top 3, which latter extends beyond the side walls of the casing 1, and has a down-turned skirt or flange 4: spaced radially from the casing and secured thereto by inverted -sha pod spacers 5, the legs of which are riveted or bolted to the casing and to said flange 4, respectively, as is shown clearly at the right of the drawing. s

This casing 1 is mounted on any suitable base, legs 6 being here shown. An annular reinforcing band 7 is arranged around the inner face of the lower part of the casing 1, and provided with a plurality of air inlet apertures 7 which register with similar apertures 7 in the casing. A gas supply pipe 8 extends upwardly through the bot- Specification of Letters Patent.

tom 2 from a horizontally disposed pipe 9 and has at its upper end'a burner 10 which may be of any suitable or desired construc tion. The pipe 9 has a threaded tapered nipple 9 at its outer end for the connection thereto of a hose or other pipe, and is provided with a cut-off cook 11 for controlling the supply of gas to the burner.

A truncated cone-shaped auxiliary casing 12 rising from an annular rectilinear integral attaching flange 12 is mounted in the lower end of the casing 1, saidflange 1:2 being positioned between the reinforcing band 7 and the inner face of the casing 1 and is secured by bolts 12 which also secure the band 7 in position. It is, of course, understood that the flange 12 has apertures registering with those in band 7 and in the casing 1, since otherwise the apertures of said members would be useless.

Arranged above the burner 10 and supported by the member 12 are a plurality of hollow cone-shaped heat collecting and retaining members 18, 14 and 15, which increase in size successively from the inner member 13 to the outer member 15 and are secured together and held'in spaced relation by tubular spacing elei'nents 16 mounted on bolts 17 which pass through the lower portion of these elements and through upstanding connectors 18 carried by the casing 12. These connectors 18 are preferably in the form of metal strips or brackets arranged at intervals to afford suitable support for the cones and yet permit the free passage of air between them.

In the use of this heater, when the gas is turned on and lighted at the burner 10, the flame enters the lower cone 13 impinging against the side walls thereof and heating it red hot in a few seconds. This red hot heating of the cone 13 destroys any fumes which may be emitted from the burner, and thus produces an odorless gas heater. Moreover, this arrangement of cones directly above the burner, prevents the heated air from coming directly in contact with the cold air until it has been intensely heated,.due to the arrangement of the cones 13, 1 1 and 15 one within the other and spaced apart a suitable distance to permit the heat from the lower and innermost to rise into the next above, until the entire cylinder is filled with intensely heated air which passes out through the space between the flange 4 of top 3 and the upper end of the casing, the cold air entering through the apertures 7 at the bottom of the casing operating to force out the hot air from the top. This arrangement insures a continuous supply of intense heat to the surrounding atmosphere.

The arrangement of cones above the gas burner and their heating by the flame produces a maximum heating effect with the consumption of a minimum quantity of gas.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

In a gas heater the combination with a casing having a closed bottom, a burner ex tended into said casing through said botgaging the inner face of said flange, said band, flange, and casing ha-ving alined air inlet openings, a plurality of hollow coneshaped members arranged one Within the other and increasing'in size from the lowest to the uppermost member, bolts passed through the lower portions of said members, tubular spacing elements arranged on said bolts between said cone shaped 'members whereby said members are supported and secured in spaced relation, and metal strips connecting the uppermost cone-shaped member with said truncated cone-shaped casing, said strips being engaged with and secured to the outer ends of saidbolts.

In testimony whereof I aflix my signature in presence of tWo witnesses.
